IARP (Inverse ARP)
Write Security: 3; Read Security: 5
The Inverse ARP (IARP) field is only present when this is a frame-relay network
interface. ATLAS always responds to Inverse ARP requests with its IP addr e ss for
the requested DLCI.
Far-End Address
Read Security: 3; Write Security: 5
The Far-End IP Address field is only present for frame-relay network interfaces,
and it is only selectable when Inverse ARP is disabled. The IP address of the
device on the other end of the virtual circuit may be specified. A static route to
the far-end network will be added using the interface Subnet-Mask if nonzero. If
0.0.0.0 has been specified for the Subnet-Mask, a default subnet mask is used based
on the class of the Far-End Address. (See also Subnet Mask on page 3-7.)
MTU (Maximum Transmit Unit)
Read Security: 5
Defines maximum number of bytes in a datagram transmitted over this interface.
RIP (Routing Information Protocol)
Configures RIP on this interface.
Mode
Write Security: 3; Read Security: 5
Allows RIP to be enabled or disabled on a per-interface basis.
If mode is Off, the following menus will not be visible.
Protocol
Write Security: 3; Read Security: 5
Sets the version of RIP being used on this interface. The options are RIP V1
and RIP V2.
Enable Atlas sends Inverse ARP packets in order to determine the IP address on
the other end of the virtual circuit. If the Inverse ARP packet is
responded to, a route is placed in the IP route table.When this field is
set to ENABLE, ATLAS dynamically sends Inverse ARP packets to deter-
mine the IP address on the other end of the virtual circuit. When an
Inverse ARP packet is not responded to, a route is placed in the IP route
table.
Disable ATLAS responds to Inverse ARP requests with its IP address for the
requested DLCI. If set to DISABLE, ATLAS does not generate Inverse ARP
request packets. In this case, the Far-End Address parameter may be
used to statically assign a route address (see Far-End Address on page
3-8).
Tx Only RIP advertisements are periodically transmitted, but are not lis-
tened to on this virtual circuit.
Rx Only RIP advertisements are not transmitted on this virtual circuit, but
they are listened to.
Tx and Rx RIP advertisements are periodically transmitted and are lis-
tened to on this virtual circuit.
